VEHICLE-HUB CASING.

SPECIFICATION forming part of Letters Patent No. 756,044, dated March29, 1904.

Application filed August '7, 1903.

To all whom it may concern.-

Be it known that I, GEORGE A. MCKEEL, a citizen of the United States,residing at the city of Jackson, in the county of Jackson and State ofMichigan, have invented a new and useful Improvement in Vehicle Casingsor Flanges and the Method of Forming the Same, of which the following isa specification.

This invention relates to sheet-metal casings or flanges for hubs havinga number of distinct objects and advantages hereinafter enumerated.

In the drawings forming part of this specification Figures 1, 2, 3, 4:,5, 6,7, and 8 illustrate the casing at various stages of its manufacturein accordance with the present invention. Fig. 9 is an end elevation ofa hub with my improved casing applied thereto, and Fig. is a verticalsectional view through the same. Y

In carrying out the present invention a sheet-metal disk is firstemployed which is capped or pressed into a cup shape 2. The

lower portion of this cup is elongated and contracted, as shown at 3.Then an outturned flange 4 is formed at the open end of the cup, and thebody portion 5 thereof is tapered, as shown. This portion 5 is afterwardelongated by drawing the metal, as illustrated in Fig. 5, and the largerportion is afterward convexed, as designated by thereference character 6in Fig. 6, the body portion being again elongated by drawing upon themetal. The next step is the making of an opening 7 in the bottom of thecup of less diameter than said bottom, forming an inturned flange 8.This flange is finally doubled inwardly against the inner face of thebody portion 5, while a marginal bead 9 is formed on the outer edge ofthe flange 4.. Fillets 10 are pressed in the metal at the juncture ofthe flange and body, and rivet-openings are formed in said flange.

If desired, the inner casing need not neces- Serial No. 168,585. (Nomodel.)

be formed as shown in Fig. 10 of the accompanying drawings.

Inuse the casing-sections are pressed upon a wooden hub 11, so that theflanges will bear against opposite sides of the spokes 12, said 5flanges being afterward united together. i

The advantages for the formation of the casing in the manner describedand the advantages of said casings may be enumerated as follows:

There is absolute perfection and correspondence in shape, a featurelacking in the malleable device of a similar character originallyemployed. There is less metal employed, and consequently a cheapening inthe cost of production as well as a lightening of weight. The casingsare, moreover, free .from flaws and have a smoother finish. Finally, theribs and fillets greatly strengthen the parts besides producing smoothfinished edges. 5

What is claimed is- 1. In a vehicle-hub, a casing comprising a taperedmetal body portion having an outstanding spoke-engaging flange providedwith an annular marginal bead, and fillets pressed 7 in the metal bodyto brace the juncture between the flange and the body portion.

2. In a vehicle-hub, a casing comprising a metal body portion having anoutstanding spoke-engaging flange provided with an annular bead, andfillets bracing the juncture between the flange and body portion.

3. In a vehicle-hub, a casing comprising a metal body portion having anoutstanding spoke-engaging flange provided with an annular marginalbead, fillets bracing the juncture between the flange and body portion,and a bead located at the end of the body portion opposite the flangedend thereof. 1

4. In a vehicle-hub, a casing including a 5 body portion having anoutstanding spokeengaging flange, and fillets bracing the juncturebetween the flange and body portion.

5. In a vehicle-hub, a casing comprising a 45 sarily include theinturned flange 8, but may I tapered sheet-metal body portion having an9 outstanding spoke engaging flange at its pressed in the metal body tobrace the junclarger end provided with an annular marginal ture betweenthe flange and body portion.
